Abstract

A method for clock distribution network control includes determining, at a first clock node of a plurality of clock nodes within a clock distribution network, a downstream clock request status. A clock request signal is transmitted by the first clock node to an upstream parent node based on the downstream clock request status. A clock buffer of the first clock node is toggled based at least in part on the clock request signal to the parent node. If the first clock node receives an asserted clock request signal from one or more downstream child nodes and clock acknowledgment signal from the parent node, a clock enable signal is asserted to the clock buffer to output a clock signal to the one or more downstream child nodes.
